I don't quite know what you mean by that, I have lots of batteries for my cordless power tools and I was told once that the more you use them the longer they last.
Well I bit the bullet and ordered it. It was that or get a bigger tank then my 90 cu. in. one and try to find a place to fill it or buy a yong heng or something. This way I can fill my guns and possibly the 90 cu. in. tank by plugging it into an outlet at home and away from power I can use the battery. Seems like a no brainer to me.
Well I posted on another forum about the bin tac and holy cow they made me feel like I just wasted my money. I get way more positive feed back from GTA !
